ISDN Configuration tasks:
1. Global Configuration -
o Select switch type (must matches the ISDN provider's switch)
o Specify traffic to trigger DDR call
2. Interface Configuration -
o Select interface specifications
o Configure ISDN addressing
3. Optional Feature Configuration

Router(config)# isdn switch-type 'switch-type'
• specifies the type of ISDN switch with which the router communicates
o basic-5ess - AT&T basic rate switches (USA)
o basic-dms100 - NT DMS-100
o basic-ni1 - National ISDN-1 (North America)
o basic-1tr6 - German 1TR6 ISDN switches
o basic-ts013 - Australian TS013 switches
o basic-net3 - Switch type for Net3 in United Kingdom and Europe
o ntt - NTT ISDN switch Japan
o none - No specific switch specified
• Other line configuration requirements vary for specific providers

Router(config)# interface bri interface-number
• Selects the interface for ISDN BRI operation

Router(config-if)# encapsulation [ppp|hdlc]
• Selects framing for ISDN BRI

Router(config-if)# isdn spid1 spid-number [ldn]
• Sets a B channel Service Profile Identifier (SPID) required by many service providers
• ldn - local dial number (optional)

Router(config-if)# isdn spid2 spid-number [ldn]
• Seta a SPID for the second B channel


ISDN BRI Simple Configuration Example

! Set up switch type, static route and dialer for ISDN
! on Cisco A isdn switch-type basic-5ess
! Selects the AT&T switch as the CO ISDN switch type
! for this router.
!
ip route 172.16.29.0.255.255.255.0 172.16.126.2
dialer-list 1 protocol ip permit
! Associates permitted IP traffic with the dialer group 1.
! The router will not start an ISDN call for any other packet
! traffic with dialer group 1.
!
! configure BRI interface for PPP;
! set address and mask interface bri 0
! Selects interface with TA and other ISDN functions
! on the router.
!
encapsulation ppp
! Use PPP encapsulation on the selected interface.
!
ip address 172.16.126.1 255.255.255.0
!
! refer to protocols in dialer-list to identify interesting
! packets dialer-group 1
! Associates the BRI 0 interface with dialing access group 1.
!
! select call start, stop, and other ISDN provider details
!
dialer wait-for-carrier-time 15
! Specifies a 15-second maximum time for the provider to
! respond once the call initiates.
!
dialer idle-timeout 1000
! Number of seconds of idle time before the router drops
! the ISDN call. Note that a long duration is configured to
! delay termination.
!
isdn spid1 0145678912
! call setup details for router
!
dialer map ip 172.16.126.2 name cisco-b 445
! Command Description
! ip Name of protocol.
! 172.16.126.2 Destination address.
! name An identification for the remote side router.
! Refers to called router.
! 445 ISDN connection number used to reach this
! DDR destination.


Verifying ISDN operation

Router# ping or telnet
• Triggers a link (assuming it is a part on interesting traffic)

Router# show dialer
• Displays current status of link, including amount of time link is connected

Router# show isdn active
• When using ISDN, displays call status while call is in progress

Router# show isdn status
• Displays the status of an ISDN connection

Router# show ip route
• Displays all routes, including static routes

Router# debud q921
• Verifies that you have a connection to the ISDN switch

Router# debug dialer
• Shows call setup and teardown activity

Router# clear interface
• Clears currently established connections

Please Help with my MRI results?I have svreee lower back pain so I went to get a MRI. My doctor is on vacation so I had the MRI results faxed to me also. i am not sure what the results mean. Please help me understand them. The conu terminates at the level of L1 and demonstrates a normal size and signal. No abdominal aortic aneurysm. No paraspinous masses. Noted are marrow end plate signal changes at the inferior end plate of L4 and superior end plate of L5 with associated disc desiccation. No disc space fluid is identified at this level. There is a small annular teat seen at this level. Disc desiccation at L5-S1 with small right paracentral annular tear also noted. The remainder of the vertebral body height, signal and alignment is normal in appearance. No abnormal signal is seen on inversion recovery sequence to suggest acute or sub acute compression fracture or acute leguminous injury.At the level of L1-2, there is minimal facet hypertrophy, but no significant abnormality.At the level of L2-3, there is facet hypertrophy, but no significant abnormality.At the level of L3-4, there is facet hypertrophy, but no significant abnormality.At the level of L4-5, there is broad-based disc bulge with facet hypertrophy with ligamentum flavum thickening and mild central spinal stenosis. No neural foraminal narrowing.At the level of L5-S1, there is annular tear with broad-based disc bulge and facet hypertrophy and ligamentum flavum thickening and mild central spinal stenosis. There is mild bilateral, left greater then right, foraminal narrowing. CONCLUSION:1.Degenerative disc disease at L4-52.Mild, left greater then right, foraminal narrowing at L5-S1.3.Mild central spinal stenosis L4-5.4.No acute or sub acute compression fracture. I am in so much pain can you please tell me what i can do or not to do. and is this serous. I am currently taking hydrocodine but it is not working well. what about muscle relaxants or somethingWhat do you think the most likley thing that i will have to do for this
